fwiw it would be easier and more useful and cheaper to just make a manual switch that would override the stock turn on setting. then you could turn it on when you wanted it to or turn it off and have it work like it would normally via the cpu turn on.

Gergman, according to past discussions here the fan settings are written in stone for OBD 1/1.5 ~ Simply follow the wire off the high speed fan relay and follow it back into the cabin. and tie a switch into the wire and ground the other side of the switch. This relay wire to the PCM is hot (so to speak) and the PCM simply grounds it. You can leave the wire still going to the PCM, just splice a switch in to ground it before it does. Then you can have it either way. Dont use the low speed relay or you will get an SES light.
